Now that we have the mechanical pod moving along the track, we need to figure out the LED lights. Firstly, each pod will be able to light up when it senses pressure. This can be controlled by a switch hooked up to a wireless battery and LED.

Next, in order to convey the idea of pods changing colour according to activity clusters, we first considered each pod carrying 3 LEDs of different colours and activating each one depending on its location on the track. The implementation details started becoming too complicated, especially if the pod needs programmable lights, meaning that the moving elements require wires connected to the BasicStamp board.

Thus, we decided on a simpler solution in which the coloured lights for each section would be statically placed on different locations on the actual track that will switch on whenever it senses a pod travelling over that section.

Colour-changes on each individual pod would have required a more complex pod construction of a non-rotating bottom layer to hit a specific switch location and use a bearing on the top to allow for pod rotation above the track.
